User.identity .name is empty

问题

I am getting user.identity.name empty in web application using forms authentication after authenticating through memberships.

I redirect it to other form but how to keep track of which user is logged in, i am not using session. Is there another way?

MembershipUser oCurrentUser = Membership.GetUser();
Response.Write(oCurrentUser.UserName); 

In this also it is giving me nullreference exception ,though it is validating properly

bCheckUser = Membership.ValidateUser(txtUserName.Text, txtPassword.Text); 

this is returning true.

回答1:

Have a look at FormsAuthentication.SetAuthCookie()

Once Membership.ValidateUser() is true you should set the authentication ticket (using FormsAuthentication.SetAuthCookie) and then you'll be able to get the User.Identity object on any other page.
